The compound used in breath analysis test for drunken driving is pottasium iodide

Answered by admin @



Answer:

Actually it's not potassium iodide.

Here is the chemical action take place in breath analyser.

When the user exhales into a breath analyzer, any ethanol present in their breath is oxidized to acetic acid at the anode:

CH3CH2OH(g) + H2O(l) → CH3CO2H(l) + 4H+(aq) + 4e−

At the cathode, atmospheric oxygen is reduced:

O2(g) + 4H+(aq) + 4e− → 2H2O(l)

The overall reaction is the oxidation of ethanol to acetic acid and water.

CH3CH2OH(l) + O2(g) → CH3COOH(aq) + H2O(l)

The electric current produced by this reaction is measured by a microcontroller, and displayed as an approximation of overall blood alcohol content (BAC) by the Alcosensor.
